Product Description

Polymer Preparation Unit Automatic Polymer Dosing System for Wastewater Treatment


Polymer Dosing System Description

A polymer dosing system is a crucial equipment designed to accurately measure and dispense polymers into a process stream. Polymers are long - chain molecules that can play a vital role in various applications such as water treatment, papermaking, and mining. The dosing system ensures that the right amount of polymer is added at the right time to achieve the desired effect.

Polymer preparation with three tanks for mixing chemical with water. Dosing port at the top for filling chemical and water; the bottom has a sewage outlet for cleaning solution tank. This dosing device used for dosing PAM (polyacrylamide) which can realize integration of PAM powder feeding, dissolving and dosing. The device integrates both automatic and manual operation.

 
 

 

Advantages of Polymer Dosing System 

 

Accurate Dosing

• The polymer dosing system is designed to provide highly accurate dosing. It utilizes advanced metering pumps such as peristaltic pumps, diaphragm pumps, or piston pumps. These pumps, combined with precise flow - control valves and sensors, can achieve a very high level of dosing accuracy. For instance, in industrial water treatment processes, the system can dose polymers with an accuracy of up to ±0.5% of the set value. This accuracy is crucial in applications where the correct amount of polymer is essential for the desired process outcome, such as in the production of high - quality paper or efficient wastewater treatment.
• The real - time adjustment capabilities of the system further enhance its accuracy. Sensors continuously monitor process parameters like flow rate, temperature, and the characteristics of the substances being treated. Based on this data, the control system can make immediate and precise adjustments to the polymer dosing rate. In a mining operation, if the slurry composition changes, the system can quickly adapt and adjust the polymer dosing to maintain optimal flocculation and solid - liquid separation.

 

 

Enhanced Process Efficiency
 

• By ensuring the accurate addition of polymers, the system significantly improves the overall efficiency of various processes. In water treatment, the proper dosing of polymers can accelerate the coagulation and flocculation processes. This leads to faster settling of suspended particles and reduces the treatment time. For example, in a municipal water treatment plant, the use of a polymer dosing system can reduce the sedimentation time by up to 40%, allowing for a higher throughput of water and more efficient operation.
• In the papermaking industry, the system helps to optimize the retention of fibers and fillers. The correct amount of polymer added can improve the paper's strength and quality while reducing waste. This not only enhances the production efficiency but also cuts down on production costs associated with raw materials.

 

Polymer Dosing System Fabricate Process

 

1. Polymer Preparation
   • The system first prepares the polymer solution. Polymers usually come in powder or liquid concentrate form. If it's in powder form, it's mixed with a suitable solvent (often water) in a mixing tank. The mixing process is carefully controlled to ensure complete dissolution of the polymer without clumping or incomplete mixing.
   • For example, in a water treatment plant, a polymer powder might be slowly added to a tank of water while the mixer is running at an appropriate speed to create a homogeneous polymer solution.
2. Dosing Mechanism
   • The prepared polymer solution is then dosed into the target process. There are different dosing mechanisms, such as peristaltic pumps, diaphragm pumps, or piston pumps. These pumps are calibrated to dispense a precise volume of the polymer solution. The dosing rate can be adjusted based on factors like flow rate of the process stream, the concentration of solids in the stream, and the desired treatment effect.
   • In a papermaking process, the polymer dosing system uses a diaphragm pump to add the polymer solution to the pulp slurry. The pump's dosing rate is adjusted according to the pulp's consistency and the quality requirements of the final paper product.
3. Control and Monitoring
   • Modern polymer dosing systems are equipped with advanced control and monitoring features. Sensors are used to measure parameters such as the polymer solution's concentration, the flow rate of the dosing pump, and the overall process conditions. The control system then adjusts the dosing rate in real - time based on these measurements to maintain optimal performance.
   • For example, in a mining operation, sensors monitor the slurry's turbidity and the polymer solution's flow rate. If the turbidity increases, the control system can increase the dosing rate of the polymer to improve the settling of solid particles.
